Low-temperature charge cut-off

Charging stops at 0 ± 5 °C and resumes at 10 ± 5 °C — the protection that keeps a winter over-charge from damaging the cells.

100 A continuous

About 1280 W at nominal voltage, with 300 A short-duration headroom for motor and compressor inrush.

4S4P expandable

Up to 4 in series and 4 in parallel per the manual — 16 batteries, about 20 kWh in total.

Capacity is chosen by application — a weekend camper and a full-time off-grid setup need very different banks. Send us your load profile and we will size it.

Compare

Same voltage, two capacities — which one?

Start with daily energy and the battery bay, then check BMS current. Bigger is not automatically better: weight, volume and recharge time change too.

Sizing calculator

How big a battery do I need?

Enter a real day of use. The calculator applies 80% depth of discharge and 85% inverter efficiency, then picks the smallest model that covers it.

Watts × hours per day. Not sure? Add up each appliance.

Planning estimate only. Check the battery bay dimensions, inverter surge and your charge source before ordering; for a bank above four packs, talk to us.

Send us the load list

Before you wire a bank

Series & parallel limits

Exceeding these limits can damage the BMS and voids the warranty. If your design needs more, talk to us first.

12V (12.8 V)

Maximum 4S4P — four in series, four in parallel, 16 batteries per bank.

24V (25.6 V)

Maximum 1S4P — parallel only. Do not connect 24V models in series.

Keep a bank uniform

Do not mix capacities or ages in one bank — each battery protects itself, not the string.

Product FAQ

Answers by model

Answers that depend on the exact model. General questions live on the FAQ page.

12V 100Ah

1280 Wh · 100 Ah

How long will the 12V 100Ah run a 12V fridge?
It depends on the fridge’s average draw and ambient temperature. The pack has 1.28 kWh nominal, about 1.0 kWh usable at 80% DOD; an efficient fridge averaging 25–40W typically runs for a day or two. Measure your own fridge before relying on an estimate.
Can I connect four 12V 100Ah in series for 48V?
Yes, up to 4S is allowed, and the model supports up to 4S4P. Use the same model and similar age, and bring all four to a similar state of charge before connecting. For a 48V system, a native 48V pack is usually simpler.
What charger does it need?
A LiFePO4 charger at 14.4 ± 0.2V CC/CV; 20A is the recommended charge current, 100A the maximum continuous. Do not use lead-acid equalisation or desulphation modes.
12V 314Ah

4019 Wh · 314 Ah

Can the 12V 314Ah run a 2000W inverter?
The pack is rated 200A continuous, and 2000W at 12V is about 170A, so it is within the continuous limit. Check the inverter’s surge rating, cable size and fuse; a 2000W inverter can pull more than 170A during startup.
What are its dimensions and weight?
383 × 193 × 250 mm and 26.5 kg (58.42 lbs). Measure the battery bay and the door/hatch opening before ordering; it is not a one-person lift for most installations.
Can I parallel it with a 12V 100Ah?
No. Different capacities share current unevenly and the smaller pack works harder. Use the same model, similar age and similar state of charge. The 314Ah supports up to 4S4P on its own.
24V 100Ah

2560 Wh · 100 Ah

Can I connect two 24V 100Ah in series for 48V?
No. The 24V models are limited to 1S4P — parallel only. For 48V, use 12V models in series (up to 4S) or a native 48V product.
What charger voltage should I use?
Use a 24V LiFePO4 charger with a lithium profile. Confirm the exact charge voltage with us for this model before charging; do not use a lead-acid equalise cycle.
Will it run a 24V trolling motor?
The pack is rated 100A continuous. Check the motor’s maximum current and your session length; most 24V trolling motors draw well under 100A, but a bow thruster may not.
24V 200Ah

5120 Wh · 200 Ah

What are the dimensions and weight of the 24V 200Ah?
Still being confirmed with the factory — we publish “On request” rather than a number we cannot stand behind. Ask us for the current drawing before you design the bay.
Can it run a 3000W inverter?
One pack is rated 100A continuous, about 2,560W at 25.6V; a 3000W inverter can exceed that. Two packs in parallel share the current (up to 1S4P), but the inverter surge and cable/fuse sizing still need checking.
How many can I put in parallel?
Up to four in parallel (1S4P), never in series. Use the same model and similar age; bring each pack to a similar state of charge before paralleling.
